What is Land Survey?

Land surveying is the process of measuring and mapping land. It is the process of measuring the geometry of the land including the boundaries, other natural and man-made objects.

Why do you want to get a land survey?

For any construction or physical infrastructure development, it is necessary to know the extent of the property, existing land features within and sometimes outside the boundary and mark if there is presence of any entities/area where caution / care should be observed. The scope of survey varies as per the project requirements. For example, house / township development vs pipeline / drainage construction.

What are different land surveying technologies used for data collection at site?

Conventional methods include using Tacheometer, Theodolite etc that uses a telescope, which measures angles and distances from points on the ground, for example, corners of buildings or trees.

Total station method involves using an electronic device called total station to measure angles and distances from points on the ground by triangulation. It electronically stores data in the instrument.

There are many other ways to carry out land surveys such as GPS (Global Positioning System) technology, laser scans, satellite imagery etc.

Aerial photography is a method that uses aerial photographs to measure and map land.

Auto-levels are used where higher accuracy in elevation is needed.

The technology is chosen based on the accuracy required of the data, location to be surveyed e.g., rural or urban areas, time available etc.

Types of Land Survey

Boundary Survey: A boundary survey is the most common type of land survey. It is used to determine the boundaries of a piece of property. This survey will usually include a physical inspection and measurement of the property. The surveyor will then create a map of the property boundaries.

Topographic Survey: A topographic land survey creates a map of the features of a piece of land, such as trees, bushes, lakes, streams etc. The surveyor will next utilize this information to generate a topographic map of the property.

Construction Survey: A construction survey is used to help plan the construction of a new building or other structure. The surveyor will measure the land and create a detailed map of the property. This map will be used to determine the best placement for the new structure and any potential problems that could arise during construction.

Location Survey: A location survey is used to determine the exact location of a piece of property. This type of survey is often used in conjunction with a boundary survey. The surveyor will use GPS technology to determine the precise location of the property corners.

Site Planning Survey: A site planning survey is used to help plan the development of a piece of land. The map created using the site planning survey will be used to determine the best way to develop the land, get grading plan and any potential difficulties that may occur during development.

Contour Survey: A contour survey is used to measure the elevation of a piece of land.  It is often used in conjunction with a topographic survey. The surveyor will use special equipment as per accuracy required to measure the elevation of the land at regular intervals. These measurements will be used to create a contour map of the property.

A digital survey of land can provide invaluable information about the size and boundaries of the property, as well as any potential easements or encroachments.

How can Infycons help you with land surveying?

Infycons provides land surveying software that helps surveyors and civil engineers with all aspects of land surveying by processing the data to generate required outputs. It includes tools to generate topographic maps instantly with automatic land features creation. Contour generation may sound simple but to replicate the land precisely, the sotware provides many utilities like digital terrain model (DTM) editing, feature to not consider certain points in the land surface or to create different types of filters. The software even helps to obtain longitudinal or cross sections with facility to obtain / correct the data as per project need. Further, many engineers have found software useful for volume computation. This feature may be useful to know the earthwork cut fill quantities or any other material. Various methods available in the software are finding its use in different applications. To know more about the software offered by Infycons, you can register for a demo using this link.
